Scope

Main Technical Content: 1. Scope This standard specifies the principles of light scattering, the monitoring principles, monitoring systems, monitoring methods, monitoring requirements, and quality assurance and maintenance for daily airborne monitoring of dust quantity on urban roads. This standard applies to the daily airborne monitoring of the spatial distribution of dust quantity on urban roads. 2. Normative References The following documents are essential for the application of this document. For any referenced documents with a date, only the version with the specified date applies to this standard. For any referenced documents without a date, the latest version (including all amendments) applies to this document. - GB/T 4208: Enclosure Protection Classification (IP Code) - CJJ/T 126: Standards for Urban Road Cleaning and Quality Evaluation 3. Terms and Definitions The following terms and definitions apply to this document. 3.1 Road Dust Loading The mass of dust, excluding visible garbage, remaining on the road surface per unit area. Note: The unit is g/m2. 3.2 Routine Cruise Monitoring System for Road Dust Loading A system for high-resolution, real-time monitoring of road dust loading on urban roads. Note: Under the aerodynamic environment created by vehicles traveling at a certain speed, the dust raised from the road surface is detected in real time by onboard sampling devices (particle monitors) and used to calculate the road dust loading based on corresponding parameters. The data from multiple vehicles are integrated to achieve high-resolution, real-time monitoring of road dust loading on the urban road network. 3.3 Terminal Equipment The smallest monitoring unit in the routine cruise monitoring system for road dust loading. Note: Used to detect road dust loading data, collect location information, etc., and transmit it to the cloud platform via wireless communication.
